TUG-FASTENER.

Specification of Letters Patent.

Patented March 30, 1909.

Application filed April 22, 1907. Serial No. 369,695.

To all whom it may concern:

Be it known that I, LEVI C. citizen of the United States, residing atMilesburg, in the county of Center and State of Pennsylvania, haveinvented new and useful Improvements in Tugd asteners, of which thefollowing is a specification.

The invention relates to an improvement in tug fasteners designed toform part of the BRADY, a

"- whiflietree tip or ferrule, to permit the convenient application ofthe tug thereto and to automatically operate to prevent accidentaldisplacement of the tug.

The main object of the present invention is the )roduetion of a tugfastener comprising a singe integral plate adapted for pivotalconnection with the whifiietree tip or ferrule and so formed as topermit the ready application of a tug when the fastener is in oneposition and prevent disengagement of the tug when the fastener is inanother position.

The invention will be described in the following specification,reference being had particularly to the accompanying drawings, in whichFigure 1 is a plan of a whiffletree end and applied ferrule, theimproved fastener being shown in tug receiving position, Fig. 2 is aside elevation of the same, Fig. 3 is a view similar to Fig. 2 with theferrule shank and fastener in longitudinal section, Fig. 4 is a viewsimilar to Fig. 2 with the fastener shown in operative position.

Referring to the drawings, my improved fastener is designed forconnection with the free end of the shank 1 of the ferrule or tip 2,which ferrule, formed in any preferred manner, is designed forconnection with the end of a whifiletree, as 3.

The fastener proper comprises a single plate 4, bent to form a centraldepression 5 which is approximately equal in depth to the diameter ofthe shank 1.. T he base wall of the depression curves upwardly at theforward end, as at 6, terminating practically in alinement with theplane of the plate. Beyond the depression the plate is extended in theform of side lips 7, extended practically in alinement with the upperedges of the depression wall, and these lips are of greatest width at apoint slightly in advance of the rear edge of the plate. From the pointof greatest width the edges of the lips curve rearwardly and inwardlyinto coincidence with the rear edge of the plate, and forwardly andinwardly into coincidence with the forward edge of the portion 6 of thedepression wall. As thus constructed the fastener in plan tapers from apoint in advance of the rear edge in both directions toward the frontand rear, thereby disposing the greatet weight of material toward therear of the fastener.

The fastener is designed to be connected to the stem 1 by a pivot pin 9passed through the walls of the depression 5 in advance of the point ofgreatest width of the fastener, the under surfaces of the lips 7 beintransversely grooved at 10 to permit t plication of the pin. The shank 1may, if desired, be reduced at 11 to receive the lower wall of thedepression 5, so that when the fastener is in position to permitapplication of the tug, the relatively lower surfaces of the fastenerand shank will be on a plane.

In use the eye of the tug is passed over the fastener with the latterarranged in longitudinal alinement with the shank, as shown in Figs. 1,2, and 3. After the tug passes beyond the fastener the latter, owing tothe preponderance of weight in the relatively rear portion, will swingon the pivot 9 and arrange itself at right angles to the plane of theshank, as shown in Fig. 4. Accidental disengagement of the tug is thusprevented, it being obvious that the fastener may be arranged in theposition shown in Fig. 1 to permit disengagement of the tug whendesired.

While showing and describing the fastener as applied to the shank ofusual whiflietree ferrule, it is obvious that it is e ually serv--iceable in the absence of the ferrule, the whifiletree proper beingreduced to provide the shank 1.

Having thus described the invention what is claimed as new, is

1. A tug fastener adapted for pivotal connection with the whiflletreeshank and comprising a plate formed with a central depression, thebottom wall of said depression curving upwardly at its forward end, lipsprojecting in opposite directions from the plate and curving downwardlyat their forward ends into coincidence with the forward edge of thebottom wall of the depression.

2. A tug fastener adapted for pivotal connection with the whiffietreeshank and co1nprising a plate formed with a central depression, tiebottom wall of said depression curving upwardly at its forward end, lipsprojecting in opposite directions from the plate and curving downwardlyat their forward ends into coincidence with the forward edge of thebottom wall of the depression, the lower portion of the whifiletreeshank being cut away to receive the bottom wall of the depression.

3. A tug fastener adapted for pivotal connection with a whifiiletreeshank and comprising an integral plate formed with a central depression,means for pivotally connecting said plate to the shank, that portion ofthe bottom wall of said de ression arranged in advance of the forwardend of the shank curving upwardly to a pint approximately in line withthe pivot, ips projecting in opposite directions from the plate andbeyond the in advance of the pivot curving downwar 1* into coincidencewith the forward edge of the bottom wall of the depres-' sion, said lipshaving their maximum width in rear of the pivot and curving from saidmaximum point into coincidence with the relatively forward and rearedges of the plate.

In testimony whereof, I afliX my signature in presence of Witnesses.
